Dark world

While I'm still working on my greyhawk saltmarsh campaign, I did have an idea the other night for a different campaign.

I recently got the fifth edition monster manual and as I was flipping through it I found the death knight entry.  That's a monster I've always wanted to use.  More so than a lich, dragon or tarasque.

I really need to create my own setting this time around.  Saltmarsh is cool and all.

During a time of troubles the world started to spin slower.  It came about because of a magical apocalyptic event.  Because of this the world gets 18 hours of darkness.

Flora and Fauna are different than they used to be.  Things grow in the dark and the muck.

The dark races came upon the land from underground as the daylight races subsided into decay and death.  The dark races did not keep to themselves but formed communities.  They are not as evil as they once were.  Unfortunately some of the vile monsters from the underworld followed them.

A long time ago there was a great war.  A Paladin was on one side, but made a deal to save his friends.  When he did he switched sides.  A castle was under siege by the Knights former battalion, which included his sister.  In the chaos he killed her and became a death knight at that instant.

The death knight has been killed and rose many times.

I'm modeling him after cobra commander and skeletor.

Because the world of men fell, there are lots of ruins to explore and magic residing in the world.

An alien race has started to inhabit the planet, they are warlike and hungry for a new world to conquer.

This is what I have so far.
